Android NDK ImageDecoder functions requires build error

Android NDK ImageDecoder functions requires build error - android

I'm trying to get byte data of png file for GLES texture.
I have my png file in app\source\main\assets.
Texture::Texture(const char *path) {
AAsset* asset = loadAsset(path);
AImageDecoder* decoder;
int result = AImageDecoder_createFromAAsset(asset, &decoder);
if(result != ANDROID_IMAGE_DECODER_SUCCESS){
__android_log_print(ANDROID_LOG_VERBOSE, "Android2", "Texture constructor create decode FAIL. path: &s", path);
}
const AImageDecoderHeaderInfo* info = AImageDecoder_getHeaderInfo(decoder);
this->width = AImageDecoderHeaderInfo_getWidth(info);
this->height = AImageDecoderHeaderInfo_getHeight(info);
size_t stride = AImageDecoder_getMinimumStride(decoder);
size_t size = height * stride;
void* pixels = malloc(size);
result = AImageDecoder_decodeImage(decoder, pixels, stride, size);
if(result != ANDROID_IMAGE_DECODER_SUCCESS){
__android_log_print(ANDROID_LOG_VERBOSE, "Android2", "Texture constructor decode image FAIL. path: &s", path);
}
//GLES create texture and bind data(pixels)
free(pixels);
AAsset_close(asset);
}
but I got following build errors:
Build command failed.

in app build.gradle file, I set minSDKVersion to 30.
I think I should link a library about ImageDecoder or do something in my CMakeLists.txt.
but I'm not sure.
target_link_libraries(
native-lib
log
android
GLESv3
box2d)

You need to link jnigraphics.
For example:
target_link_libraries(
native-lib
log
android
GLESv3
box2d
jnigraphics)
There's an example at the image-decoder sample project.

OpenCV Android Linking CXX shared library FAILED

I'm trying to build a VINS app on android platform, and I'm facing some library linking error. Seems it could not find gomp, but it's included in the target target_link_libraries in the CMakeLists.txt.
Could anyone provide me any hints on solving this problem? Many thanks!

Android Vulkan linker command failed

I'm trying to use Vulkan on Android so I had installed android ndk. I saw that in Android Studio default native C++, Vulkan is included. But whenever I build I get the following error:
C:/Users/a18/AndroidStudioProjects/vulkanSMD/app/src/main/cpp/native-lib.cpp:34:

I've tried including libvulkan.so and also tried dlopen("libvulkan.so", flags) but it is of no use.
I'm trying to get Vulkan working on android. The below code creates a vulkan instance.

layers = std::vector<const char *>({"VK_LAYER_LUNARG_standard_validation"});

vkCreateInstance(&createInfo, nullptr, &instance);

return env->NewStringUTF(hello.c_str());

Using std::bad_function_call with LIBCPP_ABI_UNSTABLE

I am trying to build a native library in my Android Studio project that uses the std::bad_function_call function.
Here's the CMakeLists.txt file I use to build my native module:
cmake_minimum_required(VERSION 3.4.1)
include_directories(src/main/cpp)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-rtti -D_LIBCPP_ABI_UNSTABLE")
add_library(
MyLib
SHARED
src/main/cpp/test.cpp
)
and my test.cpp contains the following code:
void SomeClass::SomeMethod() {
std::function<int()> f = nullptr;
try {
f();
} catch (const std::bad_function_call& e) {
}
}
with the corresponding build.gradle section:
externalNativeBuild {
cmake {
arguments "-DANDROID_TOOLCHAIN=clang", "-DANDROID_STL=c++_static", "-DANDROID_NDK_ROOT=${android.ndkDirectory}"
}
}
If I pass the _LIBCPP_ABI_UNSTABLE flag to the compiler I get a link error:
Execution failed for task ':runtime:externalNativeBuildRelease'.
> Build command failed.

If I remove the _LIBCPP_ABI_UNSTABLE flag:
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-rtti")
then the project compiles fine.
So my question is what would be the proper way to enable the libc++ unstable abi and use the bad_function_call method inside my native module?
Note: I am using Android NDK 19.

Integrating FFMPEG using cmake: undefined reference when linking libraries

I've been trying to cross-compile ffmpeg for different Android cpu archs for couple of days now and I have finally succeeded in the task. But now that I need to integrate these pre-built .so files in my project I'm facing errors which have me baffled.

Obviously the linker can not find the needed libraries, but why?!

UPDATE 2
I applied #szatmary suggestion and finally managed to to build the apk file but upon reaching the System.loadLibrary call an exception occurs indicating that the linker can not find libavutil.so.56. I tried changing the address of the library in the cmake file to actually contain the version numbered lib file to no avail:

ffmpeg is written in C, It links different than C++ due to name mangling.
remove the set_target_properties LINKER_LANGUAGE CXX stuff
set_target_properties(avcodec PROPERTIES LINKER_LANGUAGE CXX)
and wrap the lib includes
extern "C" {
#include <libavformat/avformat.h>
#include <libavutil/dict.h>
}

Android Studio CMake error (clang.exe broken )

When I open a new project that support C++ in Android Studio, It only outputs "Hello C++",And I didn't modify any code. I have tried to change the version of Android Studio and SDK. But it always show the same error.
My development platform: Windows 10
Now version: Android Studio 3.1.2
Thank you very much

The Android operating system is a mobile operating system that was developed by Google (GOOGL?) to be primarily used for touchscreen devices, cell phones, and tablets.

Android NDK ImageDecoder functions requires build error - android

You need to link jnigraphics. For example: target_link_libraries( native-lib log android GLESv3 box2d jnigraphics) There's an example at the image-decoder sample project.
